基于混沌信号频谱分布的蔡氏电路参数选择方法

A Method for Selecting Parameters of Chua's Circuit Basedon Spectrum Distribution of Chaos Signals

通过对蔡氏电路混沌信号频谱分布特征进行计算机模拟研究,得到估算其频谱分布特征值的一般公式,由此归结出具有特定频谱特性的蔡氏电路元件参数选择方法。经示例验证,该方法模拟精度较高,简便易行,可试用于双涡卷族混沌电路设计及类似混沌现象的性态分析。

In this paper, based on computer simulation of spectrum distribution of signals on Chua's circuit,the authors have obtained a common formula for estimating the spectrum distribution. And a high-precision method for selecting proper parameters to design a Chua's circuit with a specified spectrum is also presented.With the method,it is easy to design double-scroll chaos circuits and analyse the properties of similar chaos phenomena.
